BUFFER-BLOCK, CENTERING DEVICE, AND GARRY-IRON FOB CAR-COUPLINGS.

Specification of Letters Patent. Patented Blur; 22, 1910.

Application filed May 15, 1909. Serial No. 496,195.

To all whom it may. concern:

Be it known that I, Ina \VmoHT, citizen of the limited States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Buffer Blocks, Centering Devices, and

l a or stringers, in this instance of, channel l l l Carrylrons for Car-Couplers, of which the f shall be so constructed and combined that. a-

part when broken or injured can be removed and another substituted Without discarding or removing all the combined parts.

A further object is the provision of a Sim-- ple and effective centering device for the draw barwliich shall be especially adapted for application and use in connection with carshaving channel or flanged metallic center sills, and metallic end sills, though it may be applied to cars otherwise constructed,

My. vention consists in certain novelties 'of construction and combinations of parts as herein set forth and claimed.

The-accompanying drawings illustrate an example of the physical embodiment of the improvements or invention constructed according to the best mode I have so far devised for the practical application of the principle or principles.

Figure 1 is a front view in elevation. of the central portion of the car endsill with the buffer block. centering device and carry iron in place. Fig. 2 is a top plan view of Fig. 1 also showing the center sills and ends of the cheek plates. Fig. 3 is a vertical. section in elevation of Fig. 1 taken in a plane at one side of the draw bar. Fig. 4c shows front elevation, top plan, and sectional views of the buffer block. Fig. ,5 shows front ele- 'vation, side. and top plan views of one spr1ng.earrier. Fig. (3 shows frontelevation, cross sectional. and top plan views of the carry iron.

Referring to the several figures. the nui l i I meral 1 designates the metallic center sills beams spaced apart and with their flanges turned"outwardly; 2, the end sill, in this instance a channel beam with its flanges extending outwardly, and of less depth or width than the center sills. the lower flange and part of the web being removed at the center; 3, 3, vertical' netallic plates located back of the end sill; 4. the vertical edges or flanges of said plates, each bent at right angles to the body of the plate so the flange will be in frictional contact with the inner surface of the web of a channel center sill, the said flanges and webs being perforated to receive rivets; and 5 are the perforated front ends of the cheek castings which directly support the draft rigging at. the rear end of the draw bar.

The buffer block, spring carriers, and carry iron are preferably made of cast metal and are of the shapes and constructions shown in-detail by Figs. 4, 5 and 6. The

buffer block consists of a casting having a flange at -the top and sides strengthened by ribs 7, horizontal perforated flanges 8, 8, and a hollow boss or'projecting portion 9. A recess 10 is formed at the lower edge for i the draw bar. and inclined surfaces 11, 11

back of the flanges 8, 8 are fashioned to frictionally engage the lower flange of the channel end sill. "Rivets 12 passed through the flange 6 and web of the end sill secure the block in position.

Each spring carrier consists of a hollow casting having an opening of a circular shape extending to the wall 14. which wall has a small opening 15 to receive a stem or lug 16 which supports the end of a coiled spring 17, as shown: 18 is a hollow chafing cylinder closed at one end, movably supported within the opening in the casting, and inclosing part of the spring 17 An unoccupied space between the open end of the cylinder and the wall 14 allows the cylinder to move and compress the spring. The

easting has a rivet hole 19 through which, 1 and the plate is passed a rivet. t-wo rivet holes 20. 20 in line with the two holes in a flange 8 through wlnch holes are passed riv 21, 21 which secure the spring carrier to the f buffer block. A perforated flange or wing'22 extends rearwardly to a position between the I front end of the cheek casting and a flange 4: and rivets 23 are passed through the end of i the cheek plate, f ange 22-, flange 4, and the web of a' central stringer or sill. At the j lower surface of the spring carrier are two horizontal slots 24, 24: to receive the shanks j of bolts 25, 25 and above the slots are spaces to receive the heads 26, 26 of the bolts.

The carry iron consists of a fiat casting 4 with longitudinal strengthening ribs 27 at v the spring carrier and compresses. the,

. der, which latter plain end surfaces 28, through which perforations are passed the bolts 25, 25, and the 5 nuts 29 force the said surfaces into frictional contact with the-under surfaces of the spring carriers; and two perforated wings 30, each of which lies in frictional contact with the I under surface of the lower flange of a center i sill and to which flange the wing is secured by a bolt 31, as shown. The shank of the draw bar 32 is located between the project- 5 ing ends of the chafing cylinders and on curves the draw bar forces the cylinder into i i I right angles to the web; two perforated spring. When the car enters upon a tangent the spring forces the draw bar and 1 coupler, head to their normal central positions.

In the example illustrated I have shown the buffer block and the spring carriers; made separate and the spring carriers sei cured to the buffer block by rivets.

lVhat I claim is:

1. The combination with a car QIlClSllL'f of a buffer block, spring carriers located i below the ends of the buifer block, and a carry iron. detachably secured to the spring carriers; the buffer block, spring carriers, and carry iron being so disposed as to form an opening for a draw bar; and each spring carrier supporting a helical spring and chafing cylinder, which latter projects into 5 the open space for the draw bar. i-

. 2. The combination with a car end sill, of a buffer block, spring carrlers located below the ends of the buffer block and secured to the butter block, and a carry iron 'detach- & ably secured to the spring carriers; the huffer block spring carriers, and carry iron being so disposed as to form an opening for I a draw bar;-and each spring carrier supporting a helical spring and chafing cylinprojects into the open space i for the draw bar. 5 3. The combination with a buffer block f of recessed or hollow spring carriers located at the lower opposite horizontal edges of f the buffer block; and a carry iron detach- I 22, which is secured to the web of ably secured by bolts at its ends to the spring carriers; the parts being relatively so disposed as to form an opening, and said spring carriers supporting helical springs and chafing elements located within the recesses thereof, the chafing elements projecting from the said spring carriers.
